Metallic tube connections for fluid power and general use - Part 1: 24° cone connectors (ISO 8434-1:2018, Corrected version 2018-10)
This document specifies the general and dimensional requirements for 24° cone connectors using cutting ring and O‑ring seal cone (referred to as DKO) suitable for use with ferrous and non‑ferrous tubes with outside diameters from 4 mm to 42 mm inclusive. These connectors are for use in fluid power and general applications within the limits of pressure and temperature specified in this document.
They are intended for the connection of plain end tubes and hose fittings to ports in accordance with ISO 6149‑1, ISO 1179‑1 and ISO 9974‑1. (See ISO 12151‑2 for a related hose fitting specification.)
These connectors provide full-flow connections in hydraulic systems operating to the working pressures shown in Table 1. Because many factors influence the pressure at which a system performs satisfactorily, these values are not intended to be understood as guaranteed minimums. For every application, sufficient testing is meant to be conducted and reviewed by both the user and manufacturer to ensure that required performance levels are met.
NOTE 1 For new designs in hydraulic fluid power applications, see the requirements given in 9.6. Where the requirements of the application allow for the use of elastomeric seals, connector designs that conform to International Standards and incorporate elastomeric sealing are preferred.
NOTE 2 For use under conditions outside the pressure and/or temperature limits specified, see 5.4.
This document also specifies a performance and qualification test for these connectors.
Metallische Rohrverschraubungen für Fluidtechnik und allgemeine Anwendung - Teil 1: Verschraubungen mit 24°-Konus (ISO 8434-1:2018)
Dieses Dokument legt allgemeine und maßliche Anforderungen an 24°-Rohrverschraubungen mit Schneid-ring und O-Ring-Dichtkegel (kurz als DKO bezeichnet) fest, die für die Verwendung mit Stahlrohren und Rohren aus Nicht-Eisenmetallen mit einem Außendurchmesser von 4 mm bis einschließlich 42 mm geeignet sind. Diese Rohrverschraubungen sind für die Fluidtechnik und allgemeine Anwendungen im festgelegten Temperatur- und Druckbereich nach diesem Dokument vorgesehen.
Sie sind für die Verbindung von Rohren mit geraden Enden und Schlaucharmaturen an Einschraublöchern nach ISO 6149-1, ISO 1179-1 und ISO 9974-1 vorgesehen. (Festlegungen für Schlaucharmaturen, siehe ISO 12151-2.)
Diese Rohrverschraubungen sorgen in Hydraulikanlagen mit Arbeitsdrücken nach Tabelle 1 für Verbin-dungen mit vollem Durchfluss. Da der Druck, bei dem eine Anlage zufriedenstellend funktionsfähig ist, durch viele Faktoren beeinflusst wird, sind diese Werte nicht als abgesicherte Mindestwerte zu betrachten. Für jeden Anwendungsfall müssen ausreichende Prüfungen durchgeführt werden, die sowohl vom Anwender als auch vom Hersteller zu bewerten sind, um sicherzustellen, dass die geforderten Leistungsstufen eingehalten werden.
ANMERKUNG 1 Für Neukonstruktionen in hydraulischen Anlagen der Fluidtechnik gelten die Anforderungen in 9.6. Sofern nach den Anforderungen für den jeweiligen Anwendungsfall die Verwendung von Elastomerdichtungen zulässig ist, werden für die Rohrverschraubung Ausführungen nach Internationalen Normen mit Elastomerdichtungen bevor-zugt.
ANMERKUNG 2 Für Anwendungsfälle außerhalb des in dieser Norm festgelegten Druck- und/oder Temperatur-bereichs, siehe 5.4.
Dieses Dokument legt ferner eine Prüfung der Funktionsfähigkeit und Eignung dieser Rohrverschraubungen fest.
Raccordements de tubes métalliques pour transmissions hydrauliques et pneumatiques et applications générales - Partie 1: Raccords coniques à 24° (ISO 8434-1:2018, Version corrigée 2018-10)
Le présent document spécifie les exigences générales et dimensionnelles relatives à la conception et à la performance des raccords à compression à 24°, utilisant une bague de compression et un cône à joint torique (désigné comme DKO) qui sont adaptés à l'utilisation avec des tubes en métaux ferreux et non ferreux de diamètre extérieur de 4 mm à 42 mm inclus. Ces raccords sont utilisés dans les transmissions hydrauliques et pneumatiques et les applications générales dans les limites de pression et de température spécifiées dans le présent document.
Ils sont prévus pour le raccordement de tubes et de tuyaux à des orifices conformes à l'ISO 6149‑1, l'ISO 1179‑1 et l'ISO 9974‑1. (Voir l'ISO 12151‑2 pour les spécifications relatives aux raccordements flexibles.)
Ces raccords fournissent des connexions pleins débits dans des transmissions hydrauliques fonctionnant à des pressions d'utilisation telles que montrées dans le Tableau 1. À cause de l'influence de nombreux facteurs sur la pression à laquelle le système fonctionne de manière satisfaisante, ces valeurs ne sont pas destinées à être considérées comme des minima garantis. Pour chaque application, des essais suffisants sont à réaliser et à examiner à la fois par l'utilisateur et le fabricant, afin de s'assurer que le niveau de performance requis est atteint.
NOTE 1 Pour les nouvelles conceptions pour des applications de transmissions hydrauliques, voir les exigences données en 9.6. Dans les cas où les exigences de l'application permettent l'utilisation de joints en élastomères, la conception des raccords doit se conformer aux Normes internationales et incorporer de préférence des joints élastomères.
NOTE 2 Pour des utilisations en dehors des limites de températures et/ou de pressions spécifiées, voir 5.4.
Le présent document décrit également un essai de performance et de qualification relatif à ces raccords.
Kovinski cevni priključki za fluidno tehniko in za splošno uporabo - 1. del: Stožčasti priključki z naklonom 24° (ISO 8434-1:2018, popravljena različica 2018-10)
Ta dokument določa splošne in dimenzijske zahteve za stožčaste priključke z naklonom 24° z uporabo rezalnega obroča ter O-obročnega tesnilnega stožca (DKO), primernega za uporabo z železnimi in neželeznimi cevmi z zunanjimi premeri od 4 mm do vključno 42 mm. Ti priključki so namenjeni uporabi v fluidni tehniki ter splošnih načinih uporabe znotraj mejnih vrednosti tlaka in temperature, določenih v tem dokumentu.
Namenjeni so za priključitev navadnih končnih cevi in priključkov cevi v vrata v skladu s standardi ISO 6149-1, ISO 1179-1 in ISO 9974-1 (za ustrezne cevne fitinge glej ISO 12151-2). Ti priključki tvorijo priključke za poln pretok v hidravličnih sistemih, ki delujejo pri vrednostih delovnega tlaka, prikazanih v preglednici 1. Ker številni dejavniki vplivajo na tlak, pri katerem sistem deluje zadovoljivo, te vrednosti ne pomenijo zajamčenih minimalnih vrednosti. Za vsak način uporabe je treba opraviti ustrezno preskušanje, ki ga morata pregledati tako uporabnik kot proizvajalec, da zagotovita izpolnitev zahtevanih ravni zmogljivosti.
OPOMBA 1: Za uporabo novih modelov v fluidni tehniki glej zahteve, podane v točki 9.6. Kadar zahteve načina uporabe dovoljujejo uporabo elastomernih tesnil, imajo prednost modeli priključkov, ki so v skladu z mednarodnimi standardi in zagotavljajo elastomerno tesnjenje.
OPOMBA 2: Za uporabo pod pogoji zunaj določenih mejnih vrednosti tlaka in/ali temperature glej točko 5.4.
Ta dokument za te priključke določa tudi zmogljivostni in kvalifikacijski preskus.
